To enhance the operational stability and service life of tapered roller bearings (TRBs), this study investigates application surface texturing technology using laser marking to fabricate micro-dimples with controlled diameters distributions on TRB outer ring. An orthogonal experimental design was implemented systematically evaluate effects three key dimple parameters—diameter, depth, angular distribution—on tribological performance under starved lubrication. The results demonstrate that textured surfaces significantly improve friction-reducing wear resistance. Optimal parameters (diameter: 200 μm, depth: 10 interval: 0.9°) were identified, achieving a 43.6% reduction in average coefficient friction (COF) 75.7% decrease loss compared smooth bearings. These findings would offer practical approach enhancing durability reliability TRBs industrial applications.
